Passing a `va_list *'

[Roland McGrath]

Is this kosher:

#include <stddef.h>

void foo(char *s, ...)
{
  va_list args;
  va_start(args, s);
  bar(va_arg(args, double));
  ack(&args);
  ugh(va_arg(args, int));
  va_end(args);
}

void ack(va_list *args)
{
  blip(va_arg(args, int **));
}

I can't tell from the Standard.  It works on machines where a `va_list' is a
pointer into the stack, but I don't know about other schemes.
